CLAMPING DEVICE.

Application filed. August 3 To all whom it may concern Be itknown that l. lVlILLIAM T. Brin- MElSTER, a citizen of the United States. reslling at Lakewood in the coun y of Cuyahoga and hltate of Ohio. have invented a certain new and useful improvement in Clamping Devices, of which the following is a full, clean and exact description, reference being had to the accompanying drawings.

There are in use at the present time a number of devices for holding the end of a clothes line but so far as I am aware there has been developed. no device of this kind which operates satisfactorily after being used for a period of time or subjected to an undue strain. My invention provides a device of this character which overcomes these deficiencies. In the drawings accompanying; this specification and forming a part thereof I have shown, for purposes of illustration one form which my invention may assume. In these drawings:

Figure 1 is a front elevation of the base member of this illustrative form of my invention,

Figure 2 is a section on the line 22 of Figure 1,

Figure 3 is a front elevation of the entire illustrative embodiment of my invention, while Figure 41: is a section on the line 1- 1 of Figure 3.

The device herein shown comprises a base member 11 provided with a plurality of apertures 12 for the reception of screws by which the base member 11 may be secured to any suitable support and provided also with a pair of open bearings 13 each reinforced by a web 1 1' lying directly llierebelow and by a. web 15 lying thereabove but spaced laterally outwardly and continued to provide a side or end for each of the bearings 13. The device herein shown also comprises a clamping member 16 provided with a pair of trunnions 17 adapted to be readily inserted into and withdrawn from the bearings 13 to render the clamping member 16 quickly detachable from the base 11 but arranged when within the bearings 13 to support the clamping member 16 in such position relative to the base 11. as to permit the passage between the clamping member 16 and the base 11 of an extension 18 of the cable 19 which is to be clamped and which enters this space between the clamping member 16 and the base 11 by passing over one end of the clamping member 16. In order to hold tne cable 19 and the extension 18 thereof against lateral displacement the entire clamping" member 16 is irovided uponits rear face 21 with a central longitudinal groove .32 adapted to at least partially rec 'e the extension 18 and. terminating in a flu.- ing mouth adapted to retain the cable 19 almost regardless of the angle from which the cable may come.

It will he reacily understood from a consideration of the above description, that the cable 19 may be passed along the groove 212 of the clamping member 16 while the clamping member 16 is disassembled from the base 11, that the clamping member 16 may be thereafter readily assembled upon the base 11 and that the pull of the cable 19 upon the end of the clamping member 16 will then swing the clamping member 16 about its pivot upon the base 11 to cause the lower end 2% of the clamping member 16 te swing toward the base 11 and securely clamp be tween itself and the base 11 the extension 18 of the cable 19. In order to even more tightly clamp the cable I may corrugate the cooperating surfaces of the base 11 and clamping member 16 as shown herein at and 26 and as general rule I desire to so corrugate these surfaces although in some instances such corrugating may be dispensed with.

It will also he understood that pull on the extension 18 of the cable 19 at any time will swing the clamping member 16 about its pivot in the reverse direction to thus release the grip upon the cable to permit tightening of the cable and that immediately upon cessation to the pull the clamping mem ber 1.6 will return to clamping position to hold the cable in the tightened condition. It will be further understood that release of the cable by such a pull or by pressure on. the entrance end of the clamping member 16 will release the cable to permit withdrawal thereof and removal of the clamping member 16 from the base 11.

It will be apparent to those skilled in the art that the: device herein shown provides for ready reception of the cable to be clamped, securely clamps the cable positioned therewithin, and, when properly pro portioned and formed of suitable material such as maleable iron or bronze, resist-s particularly because of the method of mounting the clamping member upon the base, the deformation usual in devices of this kind and effective to readily render the de vice at least partially inoperative. It will also be apparent to those skilled in the art that the device herein shown may be modified to some extent without sacrificing the advantages thereof or departing from the spirit of my invention and that this dis-- closure is therefore illustrative only and my invention not limited thereto.

1 claim:

1. Securing means for a cable comprising: a base adapted to be secured to a support and provided on each side of its center line with a slotted bearing opening substantially directly in the plane of said base to permit removal of a trunnion therefrom by a single substantially direct movement substantially parallel to said plane, and a clamping member arranged to lie in propinquity to said base with. said cable passing over one end of said clamping member and then extending longitudinally of said clamping member between said clamping member and said base, said clamping member carrying on each side of its center line and intermediate its ends a trunnion ar ranged to cooperate with the corresponding bearing carried by said base and withdrawable through the slot in said bearing to render said clamping member quickly detachable from said base.

2. Securing means for a cable comprising: a base adapted to be secured to a support and provided on each side of its center line with a slotted bearing opening substantially directly in the plane of said base to permit removal oi a trunnion therefrom by a single substantially direct movement substan tially parallel to said plane, and a clamping member arranged to lie in propinquity to said base with said cable passing over one end of said clamping member and then extending longitudinally of said clamping member between said clamping member and said base, said clamping member carrying on each side of its center line and inte-rmediate its ends a trunnion arranged to cooperate with the corresponding bearing carried by said base.

3. Securing means for a cable comprising: a base having a back arranged to be secured to a support, and spaced flanges extending along said base and integral therewith and each comprehending a slotted bearing adapted to detachably receive a trunnion; and a clamping member arranged to lie in propinquity to said base with said cable passing over one end of said clamping member and then extending longitudinally of said clamping member between said clamping member and said base, said clamping member carrying on each side of its center line and intermediate its ends a trunnion arranged to cooperate with the corresponding bearing carried by said base.

In testimony whereof, I hereunto afiix my signature.
